Hello, today is March 25th, it's Friday, we're livestreaming from Colorado Springs.
I'm Daniel Bogdanoff from Keysight Technologies.
We know why you're here today, we're giving away actually three scopes today instead of
two as part of Scope Month. One of our previous 4000 winners respectfully declined, you may
have seen some conversation about that on the EEVBlog.
So we're going to give away two 4000 X-Series scopes 1 GHz- awesome, awesome scope. And
of course everyday we're giving away an MSOX3104T, another 1 GHz four channel scope. Both of
these have touch screens- really, really fun to use. It's all part of Scope Month.
You can enter once per day at www.scopemonth.com. By once per day, I mean once every 24 hour period,
resetting Mountain Standard Time. I think that's the only rule clarification we need at this point in the event.
We're also giving away a 6000 X-Series 6 GHz oscilloscope as part of our Test to Impress
contest, you can upload a video, telling people why you think you're the one who should get
that scope. Then we will post those videos on April 1st and the community will vote and
decide who wins that scope. So keep your videos rolling in. We're really excited, we've been
starting to review those. Again, we're going to post those Aprils 1st, voting will be open
for two weeks. At the end of two weeks, whoever has the most votes gets the scope.
Another thing, we have an internship here in Colorado Springs working with this team.
It's a great opportunity if you want to come out to Colorado Springs and work for us for a
little while. Check out the internship, we're going to link that below. I don't know if
that URL is there yet, but it will be there.
Every Friday we've been doing a "Will It" video, and this Friday, instead of posting
our own, we thought maybe you should tell us what you wish your scope should do. We've
done "Will the Scope BBQ", "Will It Sing Karaoke", "Will it be an Alarm Clock"....let us know
what you think and you may or may not get some cool Keysight swag.
So let us know, put those ideas in the comments, put them on our Facebook page, we'll be looking at those.
On April 1st, we are going to give away another scope. Just like today, we had a person decline
a scope, and we realized that voting closes March 31st at midnight. So in order to do
one last drawing that includes every single entry, we're going to give away one more MSOX3104T
on April 1st, so tune back in on that day, we're going to have another drawing.
We've been doing a scope tip everyday.Today, we're going to talk about segmented memory.
So let's take a look, we're going to zoom in on the scope here, and we'll take a look at this signal.
So here on the scope, and I know it's a little grainy, we're going to put a better higher
resolution video link of this video below. You can see here I have an RF pulse. If I
zoom out on the scope, you can see that there are a bunch of pulses here but they're pretty
far apart. Let me see if I turn up the intensity if you guys can see this better. You can see
I have a pulse every four ms or so. If I zoom out pretty far, I'm trying to capture and
see if these pulses are doing what I want them to do. If I hit signal here and I zoom
in, I can see that this pulse doesn't look like what I'd expect. And basically I've had
to undersample my signal in order to fit that whole capture on. If I hit run, this is what
the signal is supposed to look like. If you want to capture a bunch of these pulses,
what are you going to do? We have a cool memory acquisition technique
we call segmented memory, and I'm going to show you how that works.
First, I'm going to hit the acquire button. I'm doing this upside down, so bear with me.
I'm going to go to segmented memory, and I have it capturing a thousand segments, and
basically what that means is I'm going to capture a thousand times around the trigger
point. And I'm going to just check this box here, and now I'm capturing a thousand instances
of that pulse. And if I look on the right side of the screen here, I have a list and
if I scroll through this I'm going to get all the way up to a thousand.
And we notice that those pulses were every four ms, so if I've captured one thousand of those pulses
every four ms, I've actually captured four seconds of time, and ignored the dead space
inbetween. And at five giga samples a second, which is the rate of the scope for four seconds,
that's 20 Gb of data. No scope on the planet is actually able to capture 20 Gb of data
at a single time. But with segmented memory, you're able to actually selectively capture, and
store a lot, and look at a lot more time than you normally would. And now you can go through
and analyze each of these thousand segments, figure out your metrics and make sure your
system is performing the way that you want it to. And you can do this around any trigger point.
So that's segmented memory. Let's zoom back out.
We have the Oscilloscope Learning Center, there are tips for beginners, for intermediate
people, and advanced people. I even learned a cool technique on the Oscilloscope Learning Center.
Go check that out, the link is below.
We also have a blog, you saw Johnnie Hancock, you saw Taku, you saw Kenny Johnson, a crowd favorite.
All of these people, myself included, have or will have posts on this blog.
We're going to continue to update it all year, so check those posts out- of course, the link is below.
Let's go ahead and give out some scopes, shall we? So I'm going to pick three winners, the
first two are going to win a 4000X, and the third is a 3000T. And we're drawing- we're
using an online tool that we are sufficiently confident that this tool is random enough,
we looked at the algorithms, I'm not going to go into detail.
OK- who won?
So our first winner is: Dennis Hennigan, you won a 4000X, congratulations Dennis.
Justin Smith, you also won a 4000X, congratulations.
And then we have one more for the 3000T. I thought that was the same name but it's not.
Jesse Smith.
So we have two Smiths. So Dennis, Justin, Jesse, we will be in contact with you.
Thank you for watching. Make sure you like our Facebook page, subscribe to our YouTube channel,
tell your friends about Scope Month, there's only one week left.
Also, I'm on Twitter now, so check me out.
Thank you for watching. I will see you on Monday.
